Clinical Trial Summary

Goal is to determine if in adults presenting to the Emergency Department (ED) with moderate to severe acute pain, Ketamine administered at 0.15 mg/kg will provide similar pain relief to Ketamine administered at 0.3 mg/kg, with fewer adverse effects.

Description:

Study investigators will enroll participants who present to the Emergency Department (ED) with moderate to severe acute pain, and require intravenous pain medication. Participants will be double-blinded and randomized to one of the two treatment groups. Investigators aim to determine if ketamine 0.15 mg/kg IVPB is non-inferior to ketamine 0.3 mg/kg IVBP for the treatment of acute moderate to severe pain in the Emergency Department (ED). Study investigators hypothesize that in adults presenting to the ED with moderate to severe acute pain, SDK administered at 0.15 mg/kg will provide similar pain relief to SDK at 0.3 mg/kg, with reduced adverse effects.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Pain Score From Baseline to 30 Minutes Post Initiation of Drug Administration	Change in numerical pain score (NRS) from time 0 to time 30 min. The NRS ranges from 0 to 10 with higher scores indicating more pain.	30 minutes
Secondary	Change in Pain Score From Baseline to 15 Minutes	Change in numerical pain score (NRS) from time 0 to time 15 min. The NRS ranges from 0 to 10 with higher scores indicating more pain.	15 minutes
Secondary	Change in Pain Score From Baseline to 60 Minutes	Change in numerical pain score (NRS) from time 0 to time 60 min. The NRS ranges from 0 to 10 with higher scores indicating more pain.	60 minutes
Secondary	Number of Participants Who Need Additional Pain Medication at 30 Minutes	Patient request for additional pain medications at 30 minutes post initiation of drug administration	30 minutes
Secondary	Number of Patients Who Need Rescue Medications at 60 Minutes	Patient request for additional pain medications at 60 minutes	60 minutes
Secondary	Adverse Effects at 30 Min	Patients were asked if they had any adverse effects at 30 minutes including nausea, dizziness, headache, hallucinations, etc.	30 minutes
